Not at all...SPF Fail is an extremely strong condition that could be considered for outright rejection. We use it on a lot of domains that don't send mail, which keeps any spam forged from those domains from coming through. Similarly, for domains that only use a small number of outgoing mail servers we list them all in SPF. For those a failure is an indicator of forgery...which would be either virus or spam, and could thus be blocked.
SPF Pass or Unknown is next to useless, though.
